Revision 3
1.7
V
S1
:
Stalling Speed or the minimum steady flight
speedobtained in a specific configuration.
METEOROLOGICAL TERMINOLOGY
ISA
:
International Standard Atmosphere : Its temperature is
59
°
F
(15
°
C)
at sea level pressure altitude and decreases by
3.6
°
F
(2
°
C)
for each 1000 ft of altitude.
OAT
:
Outside Air Temperature is the free air static temperature. It
is expressed in either degrees Celsius or degrees
Fahrenheit.
QNH
:
Setting at the pressure corresponding to the reading of actual
airplane altitude.
Pressure Altitude :
Is the altitude read from an altimeter when the altimeter’s
barometric scale has been set to 29.92 inches of mercury
(1013.2 hPa).
ENGINE POWER TERMINOLOGY
BHP
:
Brake Horsepower is the power developed by the engine.
MP
:
Manifold Pressure is a pressure measured in the engine’s
induction system and is expressed in inches of mercury
(in.Hg).
RPM
:
Revolutions Per Minute is engine speed.
AIRPLANE PERFORMANCE AND FLIGHT PLANNING TERMINOLOGY
Climb Gradient :
Is the demonstrated ratio of the change in height during a
portion of climb, to the horizontal distance traversed in the
same time interval.
Demonstrated crosswind velocity :
Is the velocity of the crosswind component for which
adequate control of the airplane during take–off and landing
was actually demonstrated during certification tests. The
value shown is not considered to be limiting.
